IMPROVEMENT IN XTENSION-LOUNGES.

Specification forming part of Letters Patent No. 147,447, dated February10, 1874,' application tiled March 20, 1873.

To all whom it may concern:

Be it known that I, CHARLES STRE1T,of Cincinnati, Hamilton county, Stateof Ohio, have invented certain new and useful Improvements inExtension-Lounges, of which the following is a specification:

My invention relates to the class ot exten-l sion-lounges having threeprincipal parts, to Wit, the stationary frame, the sinking frame to riseand fall in the stationary frame, and the sliding frame to close overthe sinking frame when the lounge is shut up; and my invention consistsof a peculiar combination of devices or instrumentalities for raisingand lowering' the sinking frame, by which the sinking frame is liftedand depressed bodily. The

" mechanism for accomplishing this is furthermore so arranged that thevertical motions of the sinking frame are eEected Without any tendencyto move it endwise.

Figure l is a longitudinal section of my improved lounge when closed up,with the sink ing frame necessarily depressed. Fig. 2 is a longitudinalsection of the same extended, and the sinking frame raised to a levelwith the sliding frame. Fig. 3 is a cross-section of the lounge throughline X X. Fig. 4 exhibits, in skeleton perspective, the lifting devicefor opera-ting the sinking frame.

Ais the stationary frame of the lounge, and B the sliding or extensionframe, which is adapted to be fitted with the customary inattress orspring stuffing. C is the sinking frame, which is fitted to rise andfall so as to permit the extension part B to slide over it when thelounge is closed, and rise to a level with the part B when the lounge isopened I for a bed.

The part B is fitted with slides b, which rest and move upon the slidesc of the frame A. In order that the sinking frame C may be convenientlyraised and 10W- ered pcrpendicularly, and in such a Way as to have notendency to move endwise in the act of raising or lowering, I providethe swinging litters D D', hinged to the frame A at cl d, and connectedtogether to swing in opposite directions simultaneously by pitman E andcranks F F' on opposite sides of the fulcrums d d'. This is the mostdesirable way of disposing Ithe lifting mechanism; but my invention isnot limited to this particular arrangement, as the cranks may be sodisposed that the litters will swing in the same direction. To the crankF a lever, G, is attached, by which the litters D D' are operated. Theshafts or swiveling projections cl, upon which the lifters are hinged tothe frame A, are constructed and attached to the lifters D D' in themanner shown in Fig. 4. The shafts el at the crank ends pass through theframe A ofthe lounge, and the cranks F F' and pitman E are attached andoperate at the back of the lounge, as shown in dotted lines in Figs. land 2.

I claim- The combination of the sinking frame C, lifters D D', cranks FF', and connecting-pitman E, substantially as and for the purposespecified.

In testimony of which invention I hereunto set my hand.
